在油液中,空气象油泥、水及酸一样也是一种油液污染物,它能使液压系统产生如下问题。气蚀,气蚀使泵起动效率降低,增加噪音和磨损。油液中混入空气时,降低了油液的体积弹性模数,变换系统共振点位置。图1所示为当压力波从营路未端反射回来时,泵系统中产生的驻波特性曲线图,因为波的传播速度与体 In oil, air, like sludge, water and acid, is also an oil contaminant that can cause the following problems with a hydraulic system. Cavitation, cavitation reduce pump starting efficiency, increase noise and wear. Mixed with oil in the air, reducing the volume elastic modulus of oil, transform the system resonance point position. Figure 1 shows the standing wave characteristic curve generated in the pump system when the pressure wave is reflected back from the end of the camping line. Because the wave propagation velocity is proportional to the body
